Re: slave is getting disconnected in the middle of the job

sumanthnath gangavarapu, there isn't enough information in your report to perform a meaningful diagnosis. A ClosedChannelException merely indicates that the channel the agent and master were communicating on has been closed. Nothing in the report provides any indication as to how or why the channel was closed. Generally, these sorts of failures are due to system or environment issues. It isn't a problem in the code but something external that causes the connection to close. You should investigate your systems and networks so that you can isolate and determine the cause of the failure. A short, abbreviated sample of the things you should examine: Check agent logs. Check master logs. Check system logs, such as Windows Event logs. Look for high resource usage (CPU, disk, network, etc.) on master and agent machines. Investigate network issues. Look for any commonalities among the failures such as Time of day Duration of job Operating system System uptime Check the health and logs of the hosting environments. Match all of the timestamps and events up together with the failures to try and develop a picture of what is occurring. As a simple example, I saw some similar behavior on my Windows machine when it decided it was time to go to sleep. (Windows server OSes don't usually have this behavior.) I'm sorry that I'm not able to solve this problem for you, but the investigation needs to be performed at your end. If you manage to figure out the cause, I'd be curious to learn what you discovered.

Re: slave is getting disconnected in the middle of the job Hi Jeff Thompson,  Thanks for your reply. Here is what I did as a part of troubleshooting. I ran the powershell script which attempted to connect to the Linux server via 443 over and over and over again. I also changed it to 49187 after a reboot. The entire time we ran this we did not see it drop once. I believe we have layer 4 communication down. while ($true) {     "$(Get-Date);$(Test-netconnection -ComputerName <MasterNodeIP> -port 443 -informationlevel quiet)" } Next I went ahead and pushed a 5GB file via SCP from the Windows slave server to the Linux master server. The data was able to arrive on the server without an issue. I believe we have layer 7 communication down as well. I also ran the job and did some netstat information on both ends, seeing communication back and forth. As you have suggested I have checked for CPU memory issues and disc space issues and they are normal. I have captured logs can you please take a look at them.

Re: slave is getting disconnected in the middle of the job

I don't know what you intended to convey with those logs, but they don't seem immediately relevant. Perhaps, though, you've got something configured in a way that attempts to create multiple connections to the same agent. I don't see how this would cause the issue you're reporting, but it would be worth investigating. Otherwise, the logs provide nothing useful. You mention the SSH Slaves Plugin in your description above. Are you using that to connect to Windows agents? What SSH implementation are you using for Windows? This presentation contains further information on diagnosing Remoting connectivity issues. You might be able to find some information in there useful for your troubleshooting exercise. https://speakerdeck.com/onenashev/day-of-jenkins-2017-dealing-with-agent-connectivity-issues You could try varying some of your configurations to see if you can isolate components that may be interacting poorly. You could try different types of OSes or system configurations. Instead of using the Windows Slaves plugin you could try some of the other mechanisms for connecting agents on Windows. Does this fail for all jobs on Windows? Or only a subset? You could try different jobs or creating special troubleshooting jobs. You could try experiments at reducing the plugins used on a job. Or the other resources the job uses. I'm unable to reproduce this error, because of some difference in our environments or configurations. My long-running Windows job ran for an hour, reaching its proper termination time.

Re: slave is getting disconnected in the middle of the job

We managed to resolve this by adding "-Dhudson.slaves.ChannelPinger.pingInterval=2" to the Jenkins.xml of the master.   The issue was that our tests weren't printing anything out to the console,

Re: slave is getting disconnected in the middle of the job

Nush Ahmd, thanks for sharing that information. I'm glad it resolved your issue and maybe it will also help others. Just a note: hudson.slaves.ChannelPinger.pingInterval was deprecated in Jenkins 2.37. It was replaced by hudson.slaves.ChannelPinger.pingIntervalSeconds. Instead of assigning it a value of 2 in your case, you would want to assign it a value of 120 (seconds).
